Hi,
If you are facing the issue try the steps provided below and see if it helps you to fix the issue.
Step 1
Let’s boot the computer in Safe Mode and check if issue reappears. Safe mode is a diagnostic mode that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words
Safe Mode appear in the corners of your monitor to identify which Windows mode you’re using. You may refer to the article mentioned below to boot the computer in safe mode.
Advanced startup options (including safe mode).
Step 2:
If your computer works fine in safe mode, I would suggest you to perform clean boot.
Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.
